Pangram vs Plagiarisma

Pangram detects AI-generated text and images and offers plagiarism detection. Its text analysis covers material associated with ChatGPT, Gemini, Grok, Llama, and Claude, and it can highlight passages edited by AI rather than fully generated by AI. Users can submit PDF, DOCX, and RTF files, with uploads of up to 100 files at a time. Pangram says its detection works across more than 20 languages. A Chrome and Firefox extension scans feeds on sites including X, LinkedIn, Substack, Medium, Reddit, and Google Docs; listed integrations also include Canvas, Blackboard, Brightspace, Google Classroom, Moodle, Schoology, and Ashby. Pangram says submitted content is not used to train generalized AI models. Text remains stored while an account is active but can be deleted from dashboard history. The service has a free plan and a 7-day trial. Individual costs $20 per month billed annually, and Professional costs $65 per month billed annually. The site displays SOC 2 Type 2 verification by AssuranceLab.
